BACKGROUND OF THE INVENTION

The present invention relates to a sheet assembly for a cabinet and, more particularly, to a sheet assembly for a cabinet providing convenience to transportation, storage, and assemblage.

A conventional cabinet generally includes a horizontal top sheet, a horizontal bottom sheet, two vertical lateral sheets, and other sheets. Upper and lower ends of the lateral sheets are connected to two ends of the top and bottom sheets to form a frame. A rear sheet is mounted to a rear of the frame, and a door is mounted to a front of the frame, forming the cabinet with a compartment.

To reduce the space for storage and transportation, the sheets are not assembled after manufacture, so that the sheets can be stacked and packaged. Engaging holes are formed in predetermined locations of the sheets. In assembly, bolts are extended through the engaging holes of the sheets to form the cabinet. However, the assemblage requires a tool for tightening the bolts, causing inconvenience to the assemblage. Furthermore, insecure threading engagement between the bolts and the engaging holes causes loosening of the bolts and disengagement of the sheets.

In an approach to avoid the inconvenience of assemblage using bolts, the cabinet sheets include mortises and tenons. Examples of which have been disclosed in U.S. Pat. Nos. 6,883,882; 6,474,759; 6,382,748; 6,099,095; and 5,921,646. However, the mortise and tenon joint is still insecure.

BRIEF SUMMARY OF THE INVENTION

An objective of the present invention is to provide a sheet assembly for a cabinet providing convenience to transportation, storage, and assemblage while providing secure assemblage.

A sheet assembly for a cabinet according to the present invention includes a plurality of sheets having a plurality of horizontal sheets and a plurality of vertical sheets. Each of the plurality of horizontal sheets includes a first insertion/coupling section. Each of the plurality of vertical sheets includes a second insertion/coupling section engageable with one of the first insertion/coupling sections. One of a pair of the first and second insertion/coupling sections includes an insertion groove. The other of the pair of the first and second insertion/coupling sections includes a buckling slot. The sheet assembly further includes a plurality of buckle devices each having a fixed seat, a lever, and a buckle. The fixed seat is fixed to one of the first and second insertion/coupling sections having the insertion groove. The lever is pivotably connected to the fixed seat. The buckle includes an end pivotably connected to the lever. The buckle further includes a hooked portion releasably engaged with one the buckling slots. The lever is pivotable between first and second position. A spacing between the hooked portion and the fixed seat is increased when the lever is in the first position.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1-8 shows a sheet assembly of a first embodiment according to the present invention, wherein like reference number denotes like element. The sheet assembly includes a plurality of sheets and a plurality of buckle devices 3. The sheets include a plurality of horizontal plates and a plurality of vertical plates. The horizontal plates include a bottom plate 1 and a top plate 4. The vertical sheets include two lateral sheets 2. Assemblage of one of the lateral plates 2 and the bottom plate 1 will be described hereinafter with reference to FIGS. 1-7. The other lateral plate 2 and the top plate 4 can be assembled in the same way.

An insertion/coupling section 21 is provided on an inner face of the lateral plate 2 and includes an insertion groove 211. An insertion/coupling section 11 is provided on an inner face of the bottom plate 1. The insertion/coupling section 11 is engaged in the insertion groove 211 and includes a buckling slot 12.

With reference to FIGS. 2 and 3, each buckle device 3 includes a fixed seat 31, a lever 32, and a buckle 33. The fixed seat 31 includes fixing holes 311. Fasteners 34 are extended through the fixing holes 311 into the lateral sheet 2, fixing the fixed seat 31 to the inner face of the lateral sheet 2. The fixed seat 31 includes a pivotal portion 312. The lever 32 includes an end having a first pivotal portion 321 pivotably connected by a pin 324 to the pivotal portion 312 of the fixed seat 31. The lever 32 further includes a second pivotal portion 322 at a central section thereof. A gripping section 323 is provided on the other end of the lever 32. The buckle 33 includes an end having a pivotal portion 331. A hooked portion 332 is provided on the other end of the buckle 33. The pivotal portion 331 is pivotably connected by a pin 325 to the second pivotal portion 322 of the lever 32. The lever 32 is pivotable between first and second positions relative to the fixed seat 31. A spacing between the hooked portion 332 of the buckle 33 and the fixed seat 31 is increased when the lever 32 is in the first position. The spacing between the hooked portion 332 of the buckle 33 and the fixed seat 31 is decreased when the lever 32 is in the second position.

The buckle devices 3 are mounted to upper and lower ends of the lateral sheet 2 after manufacture. The sheets 1 and 2 are not assembled to reduce to the volume for storage and transportation.

With reference to FIGS. 4 and 5, in assemblage, the lateral sheet 2 and the bottom sheet 1 are engaged together by engaging the insertion/coupling sections 21 and 11.
